The main difference between Dominant Trait and Recessive Trait: A dominant trait is expressed when at least one dominant allele is present and masks the recessive trait, while a recessive trait is expressed only when tw
Dominant Trait vs Recessive Trait — Comparison Table
| Basis | Dominant Trait | Recessive Trait |
|---|---|---|
| Expression | Expressed in heterozygous condition | Expressed only in homozygous recessive |
| Allele Requirement | Needs only one dominant allele | Needs two recessive alleles |
| Representation | Capital letter, e.g., T | Small letter, e.g., t |
| Genotypes for Expression | TT and Tt both show dominant trait | Only tt shows recessive trait |
| Frequency | More common in a population | Less common in a population |
| Example | Tall plants in pea plants | Dwarf plants in pea plants |
Key Points
- Dominant alleles mask recessive alleles in heterozygous organisms
- A recessive trait can skip generations if hidden in heterozygous carriers
- Recessive traits appear more frequently when parents are related or from a closed population
- Understanding dominance explains why children may have traits not visible in parents
